Fig. 2 is the figure of freeze cycle 30 of the refrigerator 1 of expression embodiments of the present invention.As shown in Figure 2, with compressor 19, condensed device 31, transfer valve 32, refrigerating chamber with capillary the 33, the 1st evaporimeter the 10, the 1st cooling fan 11, refrigerating chamber with capillary the 34, the 2nd evaporimeter the 14, the 2nd cooling fan 35, accumulator 36, check-valves 37 connects successively and constitute freeze cycle 30.
According to this structure, constitute, switch via refrigerating chamber with the cooling running of the refrigerating chamber of capillary the 33, the 1st evaporimeter 10 with via the cooling running of refrigerating chamber by transfer valve 32,2 systems of the refrigerating chamber system of the refrigerating chamber system of stored under refrigeration chamber 5 grades and stored frozen chamber 8 etc. are alternately cooled off with the refrigerating chamber of capillary the 34, the 2nd evaporimeter 14, accumulator 36, check-valves 37.
Fig. 3 is the flow chart of flow process of defrosting of the refrigerator 1 of expression embodiments of the present invention.At first utilize Fig. 3 that the flow process of cardinal principle of the defrosting of refrigerating chamber is described.In addition, so-called here refrigerating chamber comprises stored under refrigeration chamber 5 or vegetable compartment 7, and so-called refrigerating chamber comprises switching chamber 6 or stored frozen chamber 8.
As shown in Figure 3, in order to remove, at first judge whether to have transferred to from the cooling of refrigerating chamber the cooling running (ST1) of refrigerating chamber attached to the frost on the 1st evaporimeter 10.This judgement is to become more than-18 ℃ or whether the cooling of refrigerating chamber has been carried out carrying out with first-class condition in 20 minutes according to refrigerating chamber.
Fig. 4 be begin to represent from the top refrigerating chamber sensor (below be called " R sensor ") 15 detected temperatures, the detected temperatures of RD sensor 23, refrigerating chamber sensor (below be called " F sensor ") 16 detected temperatures dynamically and the unlatching of the 1st cooling fan 11 and R heater 22 and the flow chart of closing.In addition, the detected temperature of each sensor above the expression among the project of each sensor be high temperature, below be low temperature.For example, in the item of RD sensor 23, the most left hurdle represents that temperature descends.
In addition, in Fig. 4, represent effluxion from left to right towards figure.Represent the cooling duration of runs of refrigerating chamber or the cooling duration of runs of refrigerating chamber with the part (A, B, C, D) that the longitudinal axis of dotted line is divided, for example, in Fig. 4, the part of B is represented refrigerating chamber is cooled off running.
On the other hand, the dotted line α that is depicted in the transverse axis in the hurdle of R sensor represents that the energising of R heater 22 begins temperature (detected temperatures of R sensor 15) poor in the refrigerating chamber of the Ron temperature of cooling running beginning that temperature is a refrigerating chamber and current time.This difference for example is set at 0.5 ℃, if surpassed this temperature, then as described later to 22 energisings of R heater.In addition, establishing the two-wire of the longitudinal axis in this moment of expression is a.The single-point line β that is depicted in the transverse axis in the hurdle of RD sensor 23 is the line of 3 ℃ of expressions.These 3 ℃ is to regard the temperature that defrosting finishes as, is set as the condition that R heater 22 cuts out.
As shown in Figure 4, in the A hurdle, the running with the refrigerating chamber cooling is being carried out in the detected temperatures of R sensor 15 and RD sensor 23 decline expression, on the other hand, owing to do not carry out the cooling running of refrigerating chamber under this state, the temperature in the F sensor 16 expression refrigerating chambers rises.When the cooling of refrigerating chamber running, the 1st cooling fan 11 becomes unlatching, by making the cooling of carrying out refrigerating chamber from the circulating cold air of the 1st evaporimeter 10 in the refrigerating chamber.
If satisfied the jump condition that turns round to the cooling of refrigerating chamber as described above, then the 1st cooling fan 11 switches to low-speed running, and beginning is shifted (ST2) to the cooling running of refrigerating chamber.Here so-called low-speed running is meant that for example common rotating speed is under the situation of 1900rpm, makes rotating speed drop to for example 1600 to the 1700rpm states that turn round.By like this when the cooling of the refrigerating chamber running the 1st cooling fan 11 also turn round, shown in the arrow γ of Fig. 4, can make attached to the frost on the 1st evaporimeter 10 to distil, and can improve the humidity (" humidification running ") of refrigerating chamber.Under this state, shown in F sensor 16, the temperature in the refrigerating chamber reduces gradually, and on the other hand, R sensor 15 and RD sensor 23 detect the situation that the temperature in the refrigerating chamber rises gradually.In addition, after Fig. 4, for convenience " the 1st cooling fan 11 " is recited as " R fan ".
Then, judge whether the 1st cooling fan 11 has carried out low-speed running more than 20 minutes (ST3).20 minutes as this judgment standard is to the 1st evaporimeter required minimum time of 10 defrostings.If, then continue with low-speed running the 1st cooling fan 11 not through 20 minutes.Passing through under 20 minutes the situation, judging that whether the difference of the temperature (detected temperatures of R sensor 15) in the refrigerating chamber of Ron temperature (for example 4 ℃) and current time of cooling running beginning of refrigerating chamber begins temperature (for example 0.5 ℃) big (ST4) than the energising of R sensor 22.The difference of carving Ron temperature and R sensor 15 at this moment begins the big situation of temperature than the energising of R heater 22, be under the lower situation of the interior temperature of refrigerating chamber, even make the rotation of the 1st cooling fan, also become slower because the air themperature of heat exchange is lower, the temperature of the 1st evaporimeter 10 rises, the transfer of turning round to the cooling of refrigerating chamber might need for a long time.So, with 10 heating of the 1st evaporimeter, promote defrosting (ST5) by R heater 22 is opened.That is, if observe the sequential chart of the R sensor 22 of the hypomere be documented in Fig. 4, then the part with two-wire a is that R heater 22 is opened on the border.In the case, at first R heater 22 is opened, can be prevented that the temperature of refrigerating chamber from rising because of carelessness by cooling running from refrigerating chamber.In addition, at the temperature time slack that latens that rises because the extraneous gas temperature is lower, by contrast, temperature in the refrigerating chamber rises for example more than 1 ℃, so after at the fixed time, R heater 22 is switched on, can effectively evaporimeter be heated, and can reduce power consumption.
And then, under the detected temperatures of RD sensor 23 is situation more than 3 ℃, regards defrosting as and finish (ST6), R heater 22 cuts out (ST7).Dotted line b among Fig. 4 represents to have carried out the moment of this judgement.That is, R heater 22 has only been opened the time Δ between two-wire a and the dotted line b.And, by make R heater 22 only the opening time Δ during, just the RD sensor 23 detected temperature as refrigeration defrosting sensor sharply uprise, surpass dotted line b near surpass 3 ℃, can will distil reliably attached to the frost on the 1st evaporimeter 10.
If the detected temperatures of RD sensor 23 reaches more than 3 ℃, then judge whether to have transferred to the cooling running (ST8) of refrigerating chamber from the cooling of refrigerating chamber.Whether this judgement for example is to have carried out carrying out with first-class condition in 40 minutes according to the Ron temperature of the cooling running that whether becomes the beginning refrigerating chamber or the cooling in the refrigerating chamber.Under the situation that is judged as the cooling running of having transferred to refrigerating chamber, the 1st cooling fan 11 of low-speed running recovers running (ST9) usually before this, carries out the cooling running of refrigerating chamber once more.Like this, alternately carry out the cooling running of refrigerating chamber and the cooling running of refrigerating chamber repeatedly.
On the other hand, under the situation that is judged as the cooling running of not transferring to refrigerating chamber, made for the 1st 11 further low-speed running scheduled time of cooling fan (for example 1 minute) (ST10).This is for by making the 1st cooling fan rotation scheduled time, making waste heat disperse to make the temperature of evaporimeter become even.But,, then preferentially carry out the cooling of refrigerating chamber if the request of the cooling running of refrigerating chamber is arranged in during not through the scheduled time.Through behind the preset time,,, judge whether to have transferred to once more the cooling running (ST12) of refrigerating chamber so the 1st cooling fan 11 is stopped (ST11) owing to do not need to make the 1st cooling fan to be further rotated.The benchmark of judging and the situation of step 8 are same.Under the situation of the cooling running that is judged as the refrigerating chamber of transferring to, making before this, the 1st cooling fan 11 of low-speed running recovers running (ST9) usually.
Fig. 5 is the variations in temperature of the temperature of for example having put into Hot dishes, refrigerating chamber in the refrigerating chamber that is illustrated in the cooling running of refrigerating chamber each sensor when sharply rising and the 1st cooling fan 11, the unlatching of R heater, the sequential chart of closing.
For example, in the moment of c shown in Figure 5, under the situation that the temperature in the refrigerating chamber sharply rises, R heater 22 is opened in 15 reactions of R sensor.In the case, the detected temperatures of RD sensor 23 is not followed the interior variation of temperature of R sensor 15 detected refrigerating chambers as can be known.But, if pass through R heater 22 is opened, and the 1st cooling fan 11 remained in operation, make attached to the frost on the 1st evaporimeter 10 to distil earlier, the temperature of RD sensor 23 becomes more than 3 ℃, then transfers to the cooling running of refrigerating chamber from the cooling of before this refrigerating chamber.By like this,, can prevent to be kept at the deterioration of food in the refrigerator etc. even also can transfer to the careful correspondence of the cooling running of refrigerating chamber under the situation that the temperature in refrigerating chamber sharply rises earlier.
Fig. 6 is illustrated in to make the 1st cooling fan 11 low-speed runnings (" humidification running ") backs shutter door 5a or put into Hot dishes for example and the variations in temperature of each sensor when the temperature of refrigerating chamber is sharply risen and the 1st cooling fan 11, the unlatching of R heater, the sequential chart of closing at once.
In the case, because the temperature in the refrigerating chamber rises, need to shorten the opening time of R heater 22 so consider after this R sensor 15, RD sensor 23 detected temperature to rise.So by the moment (energising of standby R heater 22) that postpones R heater 22 is opened, only with the 22 energising short periods of R heater, the step 4 that can finish at short notice in the flow chart shown in Figure 3 arrives step 7 then.By like this, even under the situation that the temperature in refrigerating chamber sharply rises, also can transfer to the careful correspondence of the cooling running of refrigerating chamber earlier, can prevent to be kept at the deterioration of food in the refrigerator etc.
Fig. 7 represents that for example the external environment condition of refrigerator 1 is in low room temperature, the variations in temperature of each sensor when temperature in the R sensor 15 detected refrigerating chambers is difficult to rise and the 1st cooling fan 11, the unlatching of R heater, the sequential chart of closing.
In the case, if be in the state that the temperature in the R sensor 15 detected refrigerating chambers is difficult to rise, then the rising of the temperature of RD sensor 23 also becomes slowly, might the cooling performance of the 1st evaporimeter 10 be reduced because of adhere to frost on the 1st evaporimeter 10 morely.So, make the refrigerator of transferring to the cooling running of refrigerating chamber from the cooling of refrigerating chamber with preset time (for example 180 minutes) time division.In flow chart shown in Figure 3, begin the difference big moment (ST4) of temperature (detected temperatures of R sensor 15) in the energising of judging R heater 22 than the temperature in the refrigerating chamber of the Ron temperature of the cooling running of beginning refrigerating chamber and current time, because it is littler than the difference of the temperature in the refrigerating chamber of the Ron temperature of the cooling running that does not also begin refrigerating chamber and current time that the energising of R heater 22 begins temperature, so judge whether to have passed through preset time (for example 180 minutes) again (ST13), under the situation of having passed through, open R heater 22 forcibly.
By like this, can provide and to cool off evaporimeter (the 1st evaporimeter) 10 of usefulness and the refrigerator that the frost on the chute 21 is removed reliably attached to refrigerating chamber.
